# Auto Video Editing(自动视频剪辑)
根据语音内容,将口播/脱口秀类视频按句子自动切分,然后按用户选择合成带字幕的最终视频。
## Prerequisites(前置要求)
在执行任何操作之前,先运行环境检测:
```bash
python3 scripts/utils.py
```
这会自动检测平台(macOS/Linux/WSL/Windows)、GPU 类型、可用编码器、Whisper 引擎,并给出诊断报告。
如果缺少依赖,提示用户安装:
- **ffmpeg**: `brew install ffmpeg`(macOS)或 `apt install ffmpeg`(Linux/WSL)或下载 Windows 版本
- **whisper**: `pip install faster-whisper`(推荐,速度快 4 倍)或 `pip install openai-whisper`
- **中国用户**加速安装:`pip install faster-whisper -i https://pypi.tuna.tsinghua.edu.cn/simple`
如果项目根目录有 `.venv` 虚拟环境,运行 Python 脚本前先激活:
```bash
source .venv/bin/activate # macOS/Linux/WSL
# Windows: .venv\Scripts\activate
```
### 平台说明
- **macOS (Apple Silicon)**: 自动使用 VideoToolbox 硬件编码加速,Whisper 推荐 large-v3-turbo 模型
- **macOS (Intel)**: 使用 VideoToolbox 编码,Whisper 使用 CPU 模式
- **Linux**: 自动检测 NVIDIA GPU (NVENC)、Intel QSV、AMD AMF
- **WSL**: 支持,自动检测 Windows 字体路径 (`/mnt/c/Windows/Fonts/`)
- **Windows**: 建议使用 WSL2 环境运行;支持 QSV/AMF 硬件编码
- **无独显 (集成显卡)**: Intel iGPU 使用 QSV 编码,AMD iGPU 使用 AMF 编码;Whisper 建议 medium 模型(而非 large)
- **中国用户**: 自动检测中国区域,使用清华 pip 镜像和 HuggingFace 镜像下载模型,也可通过 `--mirror` 参数强制启用
## Workflow(工作流程)
### Phase 1: Audio Extraction(音频提取)
对每个输入视频文件,使用 [extract_audio.py](./scripts/extract_audio.py) 提取音频:
```bash
python3 scripts/extract_audio.py "<video_path>"
```
输出:与视频同目录下的 `<video_name>_audio.wav` 文件。
### Phase 2: Speech Recognition(语音识别)
使用 [transcribe.py](./scripts/transcribe.py) 对音频进行语音识别,生成带时间戳的逐句文本:
```bash
python3 scripts/transcribe.py "<audio_path>" --model auto --language zh
```
- `--model auto`:根据硬件自动选择最佳模型(NVIDIA GPU → large-v3,Apple Silicon → large-v3-turbo,集成显卡 → medium,纯 CPU → small)
- 也可手动指定:`tiny`, `base`, `small`, `medium`, `large-v3`, `large-v3-turbo`
- `--engine auto`:自动检测 faster-whisper(推荐)或 openai-whisper
- `--mirror`:中国用户使用镜像源下载模型
- `--language`:`zh`(中文),`en`(英文),`ja`(日文)等,也可省略让 whisper 自动检测
输出:与音频同目录下的 `<video_name>_transcript.json` 文件,格式如下:
```json
{
"segments": [
{"id": 1, "start": 0.0, "end": 2.5, "text": "大家好"},
{"id": 2, "start": 2.5, "end": 5.1, "text": "今天我们来聊一个话题"}
]
}
```
**转录后检查**:如果文本中有明显的识别错误(如产品名、专有名词),应修正 transcript.json 中的文字后再进行后续步骤。
### Phase 3: Video Splitting(视频切分)
使用 [split_video.py](./scripts/split_video.py) 根据转录结果将视频切分为独立片段:
```bash
python3 scripts/split_video.py "<video_path>" "<transcript_json_path>"
```
输出:在视频同目录下创建 `<video_name>_clips/` 文件夹,包含按句子编号命名的片段文件,如 `clip_001.mp4`, `clip_002.mp4` 等。
**注意**:
- 默认 padding 为 0(片段间无重叠),避免合成时出现重复音频。
- 使用精确重编码切割(`-ss` 后置 + re-encode),确保音频在句子边界精确切断。
### Phase 3.5: Subtitle Burning(字幕烧录)
使用 [burn_subtitles.py](./scripts/burn_subtitles.py) 为每个片段烧录字幕:
```bash
python3 scripts/burn_subtitles.py "<clips_dir>" "<transcript_json_path>"
```
字幕行为:
- **自动检测语言**:中文内容自动使用中文字幕,英文内容使用英文字幕。
- **自动折行**:长字幕自动分成两行,不会超出屏幕边界。
- **竖屏优化**:字体大小按短边(宽度)缩放,字幕位置在画面 72% 高度处,适配小红书等竖屏平台。
- **中文字体优先级**:
1. 首先尝试从 Google Fonts 下载 **Noto Sans SC**(会缓存到 skill 的 `fonts/` 目录)
2. 如果下载失败,macOS 使用 **PingFang SC**(苹方);Windows 使用 **Microsoft YaHei**(微软雅黑)
- 可用 `--font-path` 指定自定义字体文件
- 可用 `--font-size` 调整字号(默认 48,基于 1080p 自动缩放)
输出:`<video_name>_clips_subtitled/` 目录,包含带字幕的片段。
**注意**:此步骤完成后,Phase 4-5 中应使用 `_clips_subtitled/` 目录而非 `_clips/` 目录。
### Phase 4: User Interaction(用户交互)
**展示片段列表给用户**,格式如下:
```
